Recycled Water and Plant Growth

Hard
Recycled Water and Plant Growth | Science Fair Projects | STEM Projects
In this experiment, we'll be testing whether recycled water helps plants grow faster. We'll measure the height of 15 radish plants over 4 weeks, watering them with distilled, tap, and recycled water.

Hypothesis

The hypothesis is that radish plants will grow more quickly when watered with recycled water.

Method & Materials

You will separate 15 radish plants into 3 groups of 5 pots each. Label the pots as “distilled”, “tap” and “recycled”. Place the pots in a location where they receive the same amount of sunlight and water them once a day with the same amount of water.
You will need 15 potted radish plants of almost the same height, distilled water, tap water, recycled water, a ruler, and a black marker pen.

Results

The results showed that plants that were watered with recycled water grew more quickly than the other plants, during the 4 weeks of observation.

Why do this project?

This science project is interesting because it shows how recycled water can be used to help conserve fresh water resources and promote plant growth.

Also Consider

Consider repeating the experiment using different types of plants, or comparing the rate of seed germination when recycled water is used.
